The Mariners' pitching staff is doing just fine these days without Randy Johnson, but many fans retain fond memories of "The Big Unit." If you're one, here's your chance to imagine living like him.

Johnson is slated to put his 5-acre, Mediterranean-style estate in Paradise Valley, Ariz., on the market on Monday, and it's worthy of the five-time Cy Young Award winner's nickname.

We'll start with the 21,148-square foot main house, which includes a living room with 24-foot ceilings and massive stone fireplace, a 12-seat dining room with adjacent temperature-controlled wine room, a chef's kitchen, a great room with beamed ceilings, his-and-her offices, a game room, a billiards parlor with a wet bar and leather-trimmed ceiling, seven bedrooms, a poker room, a fire pole from the main floor to the lower level, a 20-seat theater with marquee, ticket booth and snack bar, a recording studio, a stage, a music instrument showroom, an elevator and a three-car display garage.

There's also a two-bedroom, 1,936-square-foot guest house, a 1,746-square-foot fitness center, a covered patio with a wood-fired pizza oven, an outdoor fire pit, an eight-carmotor court, a tennis court, a pool with a spa, two-story waterslide and bathhouse, an indoor kennel, dog wash and an outdoor dog run.

"This is a very thoughtfully designed estate," listing Robert Joffe, of the Joffe Group of Berkshire Hathaway HomeServices Arizona Properties, said in a news release. "The layout works and feels comfortable, without being overwhelming. The craftsmanship is impeccable and the finish materials are some of the finest I've ever seen."
